Fantastic day with the Diablo., had seven flights now and it’s fully dialled in. Super smooth, light the Mephisto the rudder is very powerful, I ended up with 65% expo!
Will measure my final movements over the next few days, but Marius’s balance at 408mm with hopper full and main tank just about empty, is perfect.

One point of note, the canopy will go on with the nose leg up or down. 👍
